我使用工具here在azure环境中创建了kubernetes集群（v1.2.1） . 我有3个etcd节点，5个kube节点（minions）和1个kube master .

使用当前配置，我面临的问题是，在几个小时后，minion会随机离开集群 . 经过一些调试，docker守护进程本身没有在该节点上启动 .

我在ssh'g到坏节点时看到的错误消息：

CoreOS stable (899.15.0)
Update Strategy: No Reboots
Failed Units: 5
  docker.service
  install-kubernetes.service
  install-weave.service
  locksmithd.service
  docker.socket

$ kubectl get nodes 将节点状态显示为NotReady， $kubectl get events 显示在该节点上安排的pod编织API错误500 .

有些时候重新启动节点可以正常工作，但有时却没有 . 任何人都可以帮我调试这个问题或提出一些解决方案或指针吗？

$ kubectl描述节点kube-03
